Lesson 1 - Chapter 2: Monitor and Projector Connectivity Flashcards
Standard monitors and connectors use which 5 connectors?
- VGA (HD15 or DE-15)
- DVI (all variations)
- HDMI (Mini- and Micro-)
- DisplayPort
- Thunderbolt
What does a DisplayPort look like?
It looks like a USB A port but with one top right corner “chopped off”
What does a DVI port look like?
A long rectangle with small squares inside, 2 holes to screw in connector on opposite sides
What does a VGA port look like?
The “D-shell” port looks like a D with 3 row 15 pins, and 2 holes to screw the connect on opposite sides
What does an HDMI port look like?
HDMI ports look like USB A ports but with 2 of the top corners “chopped off”
What are the 5 names that a VGA connector is also known as?
- D-Shell
- D sub miniature
- DE -15
- DB -15
- HD15
What does RAMDAC stand for?
Random Access Memory Digital to Analog Converter
What does the RAMDAC do?
Converts the digital signal from the video card into analog signal (for the analog display)
Where is the RAMDAC located?
It’s a special chip on video cards (or a function of a chip)
RAMDAC does digital to analog or analog to digital?
digital to analog only
An LCD monitor requires what kind of data?
digital
What are the 2 varieties that DVI-I and DVI-D connectors come in? What’s the difference?
- Single Link (lower maximum display resolution)
- Dual Link (more pins/squares, more resolution)
What do HDMI, DisplayPort, and Thunderbolt have in common in terms of speed/monitor support, versatility, and availability?
Speed: high speed, support multiple high-resolution monitors (4k, 8k)
Versatility: carry video, sound, power, Ethernet, and data
Availability: find at least one on every new PC/monitor sold today with available adapters
What does HDMI stand for?
High-Definition Multimedia Interface
What type of HDMI connector will you find on video cards, TVs, and laptops?
Standard Type A HDMI (13.99mm x 4.45mm)
Where would you find Mini-HDMI?
tablets and digital cameras
What is the current standard for HDMI?
HDMI 2.1a (specs)
What resolutions and refresh rates does HDMI support for them?
Resolutions: Up to 8k
Refresh Rates: 60Hz for 8k, 240Hz for lower resolutions
(but ONLY with compatible hardware [monitor, display adapter] on both ends of a special high-speed HDMI cable)
DisplayPort was designed to replace what 2 connectors?
VGA and DVI (in 2006)
Between HDMI and DisplayPort, which one would PC gamers prefer?
DisplayPort because it supports higher refresh rates
If you have a single full HD or 4k display, would HDMI or DisplayPort work better?
Both work equally well (varies by older, cheap monitors and adapters supporting an earlier standard of them only [not 2.1a and 2.1])
Why would console gamers go with HDMI instead of DisplayPort?
Because most consoles don’t support DisplayPort (though there’s adapters)
What are the 2 sizes of DisplayPort?
- Standard
- Mini
what does a Mini-Display Port connector look like?
Like a square with 2 beveled corners on the 2 bottom corners
What 2 contexts are you most likely to see Mini-Display Ports?
- Older Macs (2008-2013) to connect a monitor
- Older Thunderbolt ports 1 & 2
What are Thunderbolt ‘ports’ used for? (2)
Monitors and general-purpose
(Thunderbolt is a communication standard, not a port)
Every Thunderbolt version supports what type of display?
monitors
What are 5 ways you can connect multiple monitors?
1. Laptop
2. PC
3. PC
4. PC
5. PC
- Connect the monitor to an external display port on the laptop (HDMI, DisplayPort, VGA, DVI)
- Connect a dock/port replicator to the PC, Connect the additional monitors to the dock or port replicator. Use speedy T3 or T4 connections for dock connection to the PC.
- If you have a DisplayPort 1.2 monitor port on PC, you can daisy-chain multiple DP monitors off it if the monitors have DP In and DP Out connectors
- If you have an x16 bandwidth PCIe slot available, add another display adapter card for more monitor ports
- Replace the current display adapter with one with matching ports
What connector does Thunderbolt 3 use?
USB C
What are the 6 key parts of a monitor?
- L
- T
- B
- I
- P
- If it has
- Logic Board
- Transformer
- Backlights
- Inverter
- Ports
- If it has an analog port -> analog to digital converter
Describe the 3 common LCD technologies in use today
- Twisted-Nematic (TN) - Inexpensive, high refresh rates
- In-Plane Switching (IPS) - good color fidelity, viewing angles, contrast ratio
- Vertical Alignment (VA) - compromise between TN and IPS
What are the 2 types of backlighting in a monitor?
- CCFL
- LED
What monitor doesn’t require backlighting?
OLED
